Against any random hand I am a 2-1 favorite pre-flop holding AKs. There are 1.5 small bets in the pot.
If I raise, I am raising 1.5 small bets to win 1.5 small bets. 1-1 betting odds to take down a pot that I am 2-1 to win. Those are very good odds considering I am probably ahead. If he calls, he has to call 1 small bet to win 2, so he has the odds to call, but he does not know that.

He does not know that his 64o isn't behind to 77. I have fold equity.
If he calls , I am fine with that, but he does not get to outflop me for free.
